A common false argument based in misunderstanding and fear directly blames Darwinism, atheism and evolution for such atrocities as genocide, fascism, racism and the Holocaust. Like most false arguments, this one has some degree of basis in reality, but not of the degree that can support such illogical claims.
This false argument has its grain of truth in the history of eugenics. Defined neutrally, eugenics is the study of human betterment through means of gene manipulation and control. The movement itself is said to begin with Francis Galton, a cousin of Charles Darwin. In his work Hereditary Genius, Galton states his opinion that humanity should be eugenically regimented. Charles’ son Leonard Darwin was Chairman of the British Eugenics Society between 1911-1928, and vice-President of the 1912 and 1921 International Eugenics Congresses, the first of which was an offshoot of an earlier meeting by the predominantly German-controlled International Society for Racial Hygiene.
